Correct me if I'm wrong but you should need to be in neutral if you have/want to select low range. I have never had an electronic d, but i have driven a ranger that needed to be in n to engage low.

yes when you want to engage the low range you need to have your vehicle fully stopped and put your tranny in neutral and then you can switch the transfercase to 4low. but 4 high you can turn it on at a roll under 10mph.

ok here is the deal on electronic 4wd (all 01-03 durangos which have 4wd have electronic 4wd)
1) max speed of 40 MPH in 4wd (honestly if you need 4wd it is likely not even safe to drive that fast)
2) shift on the fly, you can shift from 2wd - 4hi or 4hi - 2wd while coasting at up to 25 MPH (slower is better for the gears)
3) as stated do NOT use this on dry pavement, even wet pavement offers too much traction 4wd is meant for use in low traction such as snow or on dirt/gravel not pavement
4) 4lo is a low range which gives you more power but it does so at the cost of moving the vehicle more slowly, this is meant for high load situations such as pulling a boat up a slippery boat launch.
5) shifting into and out of 4lo must be done w/ the transmission in neutral, and vehicle speed under 10 mph, it SHOULD be done while rolling slowly (preferably btwn 0 and 5mph).
6) NEVER EVER shift while you are on the gas, only while coasting or stopped, the transfer case control module is supposed to hold the shift until all proper conditions are met however better safe than sorry IMO
